L. I LLMER BOTTLE STOPPER ADJUSTING MEANS Filed March 7, 1940 IIIIIIIIIIIIII .niIiIIIiIIl-rll lIIIr Patented. Jan. 21, 1941 UNITED, STATES.

PATENT OFFICE This invention broadly relates to freely removable closure means for mouthed wells .or the like receptacles, and more particularly pertains to a manipulative ink bottle stopper provided with an adjustably controlled quill, brushor other applicator by which drawing ink or the, like fluid may without inundation, be transferred in measured quantities between the twin points of a draftsmans ruling pen or the like implement.

When cross hatching or otherwise drawing a series of fine shade lines, an experienced draftsman usually charges his ruling pen to a precise Y initial fill of India ink without flooding to malnv r tain a desired line heft and obviate theneedfor repeatedly readjusting the penpoint spacing after each fill. To facilitate rapid productive work of this kind, it is herein contemplatedto selec tively uphold the applicator dip into the prevailing ink level to a predetermined depth by the use 20 of adjustable guard bar means preferably carried by the stopper as a unit. Such means are neatly installed exteriorly of the bottle confines and manipulatively interposed between the bottle neck and a stopper'grip portionwithout defiling 25 the fingers with ink.

Should a normally transparent glass bottle be rendered opaque by its black ink contents, the position of such guard bar visualizes the dip depth to which the quill may have been set. My stopper control is intended to be sold with each ink bottle as a commodity unit, but the same underlying adjusting principle may likewise be incorporated into a cooperating stand adapted to grippingly mount a conventional draftsmans ink bottle thereon.

A certain minimum dip depth is required to deliver a requisite fill charge into a ruling pen and the extent of this charge may be conveniently al- 40 tered by a corresponding bar adjustment whereby to successively draw a line of one and the same heft after 'each replenished pen fill. A similar bar control suffices to limit the dip when applied to an artists brush for uniformly washing a 5 drawing with India ink or the like tints.

The object of the present improvements is to devise a simple adjustable stopper appurtenance of the indicated character capable of maintaining an applicator at a substantially predetermined dip beneath the fluid level prevailing in 2; mouthed receptacle and which appurtenance shall be adapted for low cost fabrication on a rapid productive basis including the use 'of moulded plastic parts.

Alternative structural embodiments of such stopper means are exemplified in the'accompanying one sheet of drawings, in which:

Figs. '4 and 5 fragmentally depict an exterior 5 view and a partial sectional view of a modified style of stopper guard bar.

Fig. 6 cross-sectionally illustrates still another style ,of dip control in which adjustable bar means are carried by anassociated bottle stand, 10 andFig. '7 is a top view thereof with the bottle removed.

Referring more specifically to Figs. 1 to 3, the numeral l0 denotes a mouthed conventional ink well or bottle commonly used by draftsmen for filling ruling pens with India drawing ink or the like fluid whose initial level when full is indicated by H. Said shallow bottle is preferably of the usual small size that can be conveniently grasped in one hand and its stopper unit I2 manipulated in the other hand for pen filling purposes. The access mouth l3 of such bottle is generally flared outwardly to provide for a divergent conical contour and which bottle when not in use, is tightly sealed by a mated stopper against fluid evaporation or spill.

Said stopper unit is herein kept bodily demountable and preferably comprises a crown cap consisting of a stanchion component ll of which the base may be diametrically enlarged 00 to constitute a knurled grip or rim component l5. The rim bottom face may be countersunk at l6 for the centered reception of the cemented tapered cork agency I! or the like yieldable sealing material. The integral cap parts [4 and 5 I5 are designed to be die moulded from Bakelite, vulcanized rubber compound or the like'plastic and the cork may be equipped with the usual depending quill or applicator I8.

which ride upon the upturned neck shoulder 24 when my stopper is loosely entered into its bottle mouth. Said bail may further be provided with struck up V shaped tits 25 that selectively engage with any one of several cap serrations. As a substitute for the balanced stop props, the medial bail region may be made to serve a like purpose.

When the bail is manipulatively depressed into its full lined position, the entered cork I! will be held raised to fix the quill depth D, but when the bail is adjustably shifted into its topmost dotted position, the cork may descend to bring about a corresponding augmented quill dip and allow the cork to be tightly seated into the bottle neck. In this embodiment, the capped cork and its adjusted guard linkage are kept bodily removable from the bottle as a unit, and thence transferred to a ruling pen to fill the same with a measured ink charge that is dependent upon the setting.

given to the bail 22.

30 is similarly provided with a moulded crown cap comprising a knurled grip rim component 3| and a stanchion component 32, the latter being preferably transversely slotted at 33. The rim perimeter may be oppositely recessed as at 34 and have a spring actuated detent 35 inserted into a suitable cap socket. I may be countersunk for the reception of the tapered cork 36.

In this instance, the guard bar 3'! is fabricated from corrugated metallic strip stock and is preferably given a U-shaped contour of which the respective legs are slidably nested within a contiguous guide recess 34, the guard yoke being slidably entered through the slot 33, as shown. By adjustably depressing or raising this bar yoke into a different retained position, the depending cork quill will be selectively shifted into an altered dip position to follow up the ink level as the supply gradually becomes depleted and thereby substantially maintain a constant charge for transfer to the ruling pen. When the ink supply reaches a level too low for an adequate quill charge, the bottle may be refilled and the bar appropriately readjusted to prevent pen flooding.

The use of moulded plastic together with strip stock components serves to hold down fabrication cost to a degree that allows of incorporating my adjustable guard appurtenances to stoppers for drawing ink bottles as a unit without necessitating a substantial increase in the retail selling price thereof.

Figs. 6 and 7 disclose a supplementary bottle base 39 of moulded plastic, preferably vulcanized rubber compound comprising a substantially round foot plate 40 including checkered pad faces 4| designed to firmly rest upon a normally inclined drawing table without slip. Within such plate margin there is die cast, a substantially. endless bottle centering flange preferably shaped to comprise perimetrically spaced but laterally yieldable jaws such as 42 of which the upstanding bore face may be undercut as at 43. Such flange spacing facilitates the insertion or removal of a gripped bottle.

Adjoining one such'jaw is a tubular post or boss 44 which may have moulded therein an inbuilt metallic U-shaped strip 45 provided with opposed closely spaced corrugations or teeth such as 46 and 41. Telescopically cooperating with such teeth is an extensible standard or prop 48 also shaped from strip stock of which the upper prop end may terminate in a return bend loop that mounts the hinge pintle49-therein. Each super- The bottom face of said cap imposed lower twin end of such strip stock is respectively shown corrugated to adjustably engage with and be retained by said teeth 46 and 41 and thereby allow the pintle to be manipulatively raised or lowered stepwise. The upper end of the standard may be offset to provide for a ledge 50. Pivoted'to said pintle is a leverized guard bar 5| which may be provided with a stop lug 52 adapted to rest upon said ledge when the guard bar assumes its full-lined operative position beneath the stopper cap rim 50. Such lever may -be swung in the arrowed direction but if desired may also be rigidly affixed to said standard. By squeezing the spaced prop corrugations together, they may readily be disengaged from their mated teeth to adjust the dip D.

It will be obvious that the function of the adjustable guard lever 5| is identical with the corresponding members 22 and 31 previously described. As indicated in Fig. 6, the stopper cork 53 may be tubular and have a cylindrical ferrule 54 of an artist's brush, snugly entered therethrough. The tip, of the brush bristles 55 then adjustably dip into the bottled fluid 56 to an extent D' as fixed by the prop adjustment and a brush handle length 51 may extend outwardly through the stopper stanchion 58, as shown.

As an understructure, the one-piece base plate 39 stabilizes the shallow bottle 59 against upset, and is particularly useful where ink containers of this kind need to be shiftably placed within the confines of a large sheet that is being drawn upon.

Should a loosely stoppered ink bottle rest upon a sharply inclined drawing table, it is preferred to provide my base foot flange 40 with apertures such as 6| or with inset slots such as 52 or the like through which a, thumb tack may be entered into engagement with an underlying drawing board, thus further stabilizing said bottle against inadvertent upset. As an inherent attribute of my flange when moulded from rubber compound, a tack may also penetrate therethrough without any special aperture provision.

Where the need for a measured applicator dip is of no significance, the forked guard lever 5| may be thrown into its inoperative position 5|, it being emphasized however that by virtue of my telescopic prop 48, the cork can readily be pressed home to seal the bottle mouth against leakage without necessarily throwing said lever into its 5| position. It will be evident that my bottle base 39 may also be utilized in conjunction with the Figs. 1 or 4 style of stopper without resort to any telescopic prop such as 48.

As will be understood by those skilled in this art, the disclosed guard bar features are likely to find application o purposesv other than drawing ink bottles and that various modifications in the structural details thereof may be resorted to in likewise carrying out the same underlying principles, all Without departing from the spirit and scope of my invention herein described and more particularly defined in the appended claims.
